How to Use HONGFA 24V 16A DC HF115FK/024-2ZS4T 8-Pin SPDT Power Relay
Solder the relay onto your PCB according to the 8-pin footprint, then apply 24 V DC across the coil pins to energize. Connect your load between the common (COM) and normally open (NO) or normally closed (NC) contacts, ensuring the current does not exceed 16 A resistive at 250 VAC. Use a suitable driver or transistor if your control circuit cannot supply the coil current directly.
